Description

High-density passive breakout DAC for short-reach, in-rack connections. Converts one 200G OSFP port into two independent 100G QSFP28 copper links with ultra-low latency and zero power draw. Ideal for TOR aggregation and cost-effective leaf/spine breakouts up to 2 meters.

Features

- Cost-effective 200G to 2x100G breakout without optics
- Ultra-low latency passive copper link
- Standards-based CR interoperability
- Tool-less, plug-and-play deployment

FAQs

Q: Is this cable active or passive?
A: It is a passive twinax DAC with zero power consumption and ultra-low latency.

Q: What ports does it connect?
A: One 200G OSFP port on the host side to two 100G QSFP28 ports on the device side.

Q: Will it work with different vendors’ equipment?
A: It follows Ethernet CR standards, but vendor-specific coding policies may apply. Verify platform DAC compatibility and coding requirements.

Q: Do I need to configure FEC for this DAC?
A: FEC is handled by the host platforms per their defaults and standards. No settings are required on the cable itself.
